Flower food

In some parts of the U.S., Black Locust is an invasive, but in other places it's native.

I tried the flowers by themselves once, and they were so good, I thought about eating them for weeks, months...

Some recipes:
Black Locust flower doughnuts
Black Locust flower fritters (with Italy pics!)
Another recipe with more detailed step-by-step pics!
A Polish version!
Black Locust flower pancakes

From what I understand, just the flower is okay; the rest of the tree is poisonous.
